Struct LuaFunction 

pub struct LuaFunction { /* private fields */ }

Handle to a Lua-callable value (Value::Closure or Value::Native) pinned in the host root pool. Copy-able — clones share the same HostRootTicket.

Becomes stale (panics on call) after Lua::unpin / Lua::unpin_all.

Implementations

impl LuaFunction

pub fn ticket(self) -> HostRootTicket

The underlying HostRootTicket. Facade-author use only.

pub fn call<A, R>(self, lua: &mut Lua, args: A) -> Result<R, LuaError>

where A: IntoLuaArgs, R: FromLuaValue,

Call this function with the given typed args; decode the (first) return as R. Use LuaFunction::call_multi for the full result vector.

pub fn call_multi<A>( self, lua: &mut Lua, args: A, ) -> Result<Vec<Value>, LuaError>

where A: IntoLuaArgs,

Call this function; return all results.

Trait Implementations

impl Clone for LuaFunction

fn clone(&self) -> LuaFunction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for LuaFunction

impl Debug for LuaFunction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl IntoValue for LuaFunction

fn into_value(self, vm: &mut Vm) -> Value

Convert self to a Lua Value, interning strings or allocating other GC-managed types via vm.heap as needed.

impl PinnedHandle for LuaFunction

fn ticket(&self) -> HostRootTicket

The ticket this handle wraps.
